ABSTRACT:
A transmission rope for driving movable mirror modules of an image scanning device is disclosed. One end of the transmission rope is located at a locating member. The other end of the transmission rope is first wound on a guide wheel of the second movable mirror module and then held by a rope holder of the first movable mirror module and then the transmission rope is sequentially traveled through several auxiliary guide wheels and a driving motor and then wound back onto the guide wheel of the second movable mirror module and finally fixed at a tension adjuster. The section of the transmission rope between the rope holder of the first movable mirror module and the guide wheel of the second movable mirror module and between the guide wheel of the second movable mirror module and the locating member has better tensile strength than that of the other section of the transmission rope so as to minimize the length deformation during driving the first and second movable mirror modules.
